Arsenal chase Silva

Silva joined Milan for £33m in June and has scored four goals so far -- all in the Europa League.

With Barcelona also keeping a close eye on the 21-year-old's development, there are whispers that Milan could be forced to sell to reduce growing debts after their summer transfer splurge.

The report states that the Rossoneri are searching for more investment to cover costs as they look increasingly likely to miss out on a Champions League windfall next season.

Saints want Koulibaly

Southampton will revive their bid for Napoli defender Kalidou Koulibaly in January after failing to strike a deal for the Senegal international in the summer.

According to TalkSport, the Saints see Koulibaly as an ideal replacement for club captain Virgil van Dijk, who remains a target for Liverpool.

They could face stiff competition for the 26-year-old, however, with Chelsea, Everton and Barcelona expressing an interest in recent months.

Tap-ins

-- Arsenal, Chelsea and Liverpool will need to act fast if they want to snap up Arturo Vidal from Bayern Munich, reports TalkSport. The Chilean midfielder is a target for Inter Milan, who are keen to finalise a January transfer.

-- Tottenham will step up their interest in Ross Barkley when the transfer window reopens after an injury-hit campaign for the club's midfielders. Victor Wanyama and Mousa Dembele have both been struggling with knocks, prompting Mauricio Pochettino to renew his pursuit of the Everton man, claims the Daily Mirror.

-- Real Madrid apparently have the inside track on up-and-coming Brazil star Alan. AS reports that Los Blancos have already reached a verbal agreement to acquire the Palmeiras youngster, who is on duty with the Selecao under-17 team in India.
